[sane-devel] samsung smfp, local scanimage works but not via net

[Ruediger Meier]

Hi,


I have a Samsung SCX-4833FR with libsane-smfp.so.1 installed on saned 
server.

scanimage works locally on the server but not on saned client:

$ scanimage >/dev/null
[...]

The funny thing is that xsane (same libsane) does the job. So I've 
looked at saned's debug output to see what both clients are doing 
differently.
As far I can see it looks like xsane and scanimage are sending some 
different parameters to saned but I could not find out something 
specific.

So would be nice if somebody of you could log at the attached logs to 
point me to the right direction.
Maybe it's even a bug in scanimage.


thx,
Rudi
